(el. 28o- 41) 16 Claims.

This invention relates to improvements in collapsible childs carriage.

The main objects of this invention are:

First, to provide a collapsible childs carriage which is easilycollapsed and erected and which is quite compact when collapsed.

Second, to provide a structure having these advantages in which the bodyof the carriage may be easily detached from the running gear frame andat the same time one when attached is very securely retained.

Third, to provide a collapsible carriage in which the parts areeffectively locked both in erected position and in collapsed position.

Fourth, to provide a structure of this character in which the detachablebody may be reversely positioned on the chassis or running gear frame.

Fifth, to provide a collapsible carriage in which all four of the wheelsare springably supported for independent springing or what might becalled knee action and at the same time are s supported as to providestability and effective and easy steering and manipulation on curbs,steps and the like.

Objects relating to details and economies of the invention will appearfrom the description to follow. The invention is defined in the claims.

A structure which is a preferred embodiment of the invention isillustrated in the accompanying drawings, in which:

In the embodiment of the invention illustrated, I provide a running gearor chassis :frame `comprising side bars I connected by the cross bars ormembers 2 to provide a fairly rigid-like frame. The side bars I areformed of flexed stock and are arranged vertically edgewise. The frontand rear wheels 3` and 4 are, as shown, of the conventional rubber-tiredtype.

The body illustrated, designated generally by the numeral 5, is formedof a suitable frame and a covering of leather or fabric. It will beunderstood, however, that this might be of any desired structureormaterial but it should be of such dimensions as to removably t withinthe side members I. A

The frame desirably comprises top side .members 1, the walls being cutaway or conformed at 8 to provide a handhold 9 on each side. The top kIE! is of the collapsible bowed type and is pivotally mounted on bracketsII. The top is provided with an anchoring link I2 adapted to en gage thebolt I3 having a thumb screw I4. This prevents the top from accidentallyswinging on its pivot.

The body is provided with pairs of downwardly facing hooks I5 which areadapted to engage over the upper edges of the inwardly offset ends I6 ofthe side bars I, see Fig. 6. The offsets I'I limit the longitudinalmovement of the body on the side bars. The body is detachably secured tothe side bars by means of catches I8, see Fig. 5, which are pivoted atI9 on the brackets 20 projecting from the sides of the body.

'Ihe bail-shaped release member 2i is mounted on the sides of the bodyin convenient position for grasping, the arms 22 of the release memberbeing slidably supported in the brackets 23 and being connected by links24 to the latches, as shown in Figs. 1 and 5.

, lateral twisting movementf The structure Coiled springs 25 areprovided to yieldingly urge or bias the release members downwardly andthereby urge the latches into engaging position. The upper ends of thesesprings engage the upper arms 26 of the brackets 23 while the lower endsof the springs engage thrust members 2'! secured to the arms 22 of therelease member. The lower arms 28, of the brackets 23 restrain or .limitthe Amovement yof the thrust member 21.

When it is desired to release the body from the running gear theoperator grasps, the cross portion of the release member and this ispositioned in such relation to the top side bars` Il oi the frame thatthey may be .s imutaneollly grasped and an upward pull with the fingersreleases the body. When the body .1'5 deligngd from the frame it may beused as abass'inet or as a convenient means for carrying a child intothe house or apartment or :f or placing it on the seat of an.automobile., l

The running gear portion of the, Qlrriage may be eolla'psed as 'Shown iniig.v 4. tor convenient handling; orl storage independently efthe-body.`

The front Wheelv hangers ete.- simultaneously actuated with the, rearwheel hangers, this being accomplished, in the embodiment illustrated,by providing an auxiliary actuating lever `44, which is pivoted tol theside bars at 45,` they lower` ends cf this auxiliary lever beingvconnected tothe front wheel hangers by the link 46 pivoted to the lowerends ofthe auxiliary actuating lever` at 41 and tothe upper endsof; thefront wheel hangers at i84 To holdy the parts; in erected position,V l;provide U-sectioned loci;v members l4,9 which are pivoted atl lill` tothe sidev members lof the handlefand Vare adapted to embraeethe handleand. also, theupper ends of the actuating lever 33 asis clearly shown inthe drawings. With the .parts lthus engaged the parts areeffeotivelylockedin erectedposition;

To lock the parts in ollapsed pos-iti.01.11., the.

actuating levers 33 are provided with laterally projecting arms 5l withwhich the handle side members are aligned when the parts are incollapsed position as shown in Figs. 2, 4 and 8, the locking members orkeepers 49 being then engaged with the arms 5I thereby locking the partsin their collapsed position and permitting the collapsed structure beinghandled or carried by the handle. It :will `be noted that in .collapsedposition the wheels swing up on the sides of the body thereby providinga very compact structure.

'Ifhelocliing members or keepers 49 are provided with 4springs 52', seeFig. '7, so that they are norlcligod to engaged position but may be ree-lealpressing on the upper ends thereof.

In the .embodiment of my invention shown in Eig. 9 the wheels Yareprovided with axles 53 and are supported entirely by the springs 54although torsion rods might be desired in this embodiment. Toaccommodate the axles, the body is formed with `flexible end portions.55 having swingable bottom sections 56, see Fig. 9;. This permits theends of the body to. collapse upwardly when the wheels are collapsed.

.the embodiment of my invention shown in Figs. 10 to 14 inclusive Iillustrate a structure in which themeansfordetachably securing the bodyto .the .running gear 4frame `or chassis is located under the .body andis mainlyv carried by the running gear ,f rarne. In this embodiment, therunning gear frarne or chassis Vdesignated. generally by .the numeral 6Dis generally rectangular and termed or angle iron arranged with theangles facing inwardly downwardly. The frame comprises a pair of opposedside members Si and @Omleoting .end members or cross members 62, these.parts Ybeing formed 'integrally or integrally secured together as bywelding, no joints being illustrated. Thejbody 5' is provided with adownwardly projecting "headed stud 5 3, four being illustrated, adaptedto project into the frame as is clearly illustrated in Figs. l1 and 14.The body is 'provided with vwear plates G4' adapted to rest on tlrefram-e and'protectgthe covering of the body or thenish ofthe body. Apair of locking bars are mounted onthe under sides` of the horizontallegs ,ofthe side 'members li of the frame by mea-ns of1 the headedrivets4 E6; which engage the `diagonally disposed slots in the lockingbars s o that, as the locking bars are shifted longitudinally ltheyA aremoved into and out of engagement with the studs F513. Qn the body.

The 'locking bars 65' are actuated by means of the lever 68 which is,pivoted at 63 on the bracket 18-projectingiortvardly from the rear crosspiece 62` of the frame. Achandle 'H' is secured to this lever andprojects rearwardly beyond the rear cross. `piece and through a slot 'l2in the downwardly `projecting legs 'i3 of: the rearcross piece, the-slot having an enlargementat one endv to providel Aa keeper 'M1' 4forthe lever in its engaged position. The lever is springableA and isyieldingly held in .engagement with the keeper when in registrytherewith.

The locking `bars-16:5' are. provided with headed Studs 75 which engageslots 115@ on the lever, permitting .ti-,1ey swingingrof, the iever.With this a1- rangementithe; lodging bers whenY actuated infonedirection mor-ed laterally Outward te die engage the studs 63 and whenmovedv in the other direction. aremoved laterally inward intoengagetherewith. This provides. va very secure locking engagement .andhas the advantage over the other embodiment shown, of. having the,retaining means for thel 4body effectively concealed;

As in the other described embodiments, .the body may be positioned toface either way. If desired, the body may be provided with a seat but Ihave not illustrated that. The structure may -be safely collapsed whileoccupied and there is no tilting of the body in collapsing. It will benoted that the handle folds downwardly in collapsing rather thanswinging over the top of the carriage which might result in injury ifreleased accidentally. In collapsing, the handle swings downwardly andalso there is a downward movement .of the body as the wheels swing up atthe sides thereof and thiscan be readily controlled.

As stated, the structure is effectively locked in both collapsed anderected positions for handling in either position. If desired, insteadof providing straight axles with collapsible portions for the body, dropaxles can be used which avoids the necessity of providing thecollapsible feature of the body. I have not illustrated such a structureVas it is believed that its use will be clearly understood.

I have illustrated and described my invention in embodiments thereofwhich I have found to be highly practical. I have not attemptedtoillustrate or describe other embodiments or adaptations as it isbelieved that this disclosure will enable those skilled inthe art toembody or adapt my invention as may be desired.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:
